I've had limited success attempting to add realistic mountains and tunnels to my layouts in RR-Track v5. I understand how the "Point" contour works, but I've had no success at all with the Open Line and Closed Line contours. Frankly, even the Point contour results in odd effects where it intersects the track, and the edge of the terrain base.
I actually managed to create a realistic slope by first extending the terrain, placing a point, and then retracting the terrain to its original extent, leaving the point outside its base. (I had to "trick" the program because this is normally not allowed.) So experienced layout designers: What are your tips for an effective work-flow for creating terrain in RR-Track?
Is it possible to create custom mountains and tunnels as polygons?
Finally I also have a little experience with SCARM. I've seen some great 3-D layouts created with that program, but I watched a youtube tutorial about forming terrain in SCARM and it looks quite complicated. I wish they could make it as easy as it is in Trainz (a RR simulation game.) In Trainz you can raise mountains in no time at all, and the "smart" interaction with the track is excellent. Thanks in advance for your help!
